11-saltstack 之jinja

1.定义jinja模板

[root@salt-master base]# vim /srv/salt/base/dns.sls 
/etc/resolv.conf:
  file.managed:
    - source: salt://files/resolv.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja                         # 出现template就表示模板
    - defaults:
      DNS_SERVER: 10.10.10.10         # 变量列表


--------------------------------------------------------------------------
官方网站：jinja.pocoo.org

模板文件里面变量使用{{名称}}
1.变量使用grains: {{grains['fqdn_ip4']}}
2.变量使用执行模块：{{salt['network.hw_addr']('echo')}}
3.变量使用pillar: {{pillar['apache']['PORT']}


1.file状态使用template参数
  - templat: jinja
2.变量列表
  - defaults:
    PORT: 8080
3.模板文件里面变量使用{{名称}}
  {{PORT}}

 2.编辑变量文件

[root@salt-master base]# vim files/resolv.conf 
search DHCP HOST
nameserver 120.196.165.24
nameserver 211.136.192.6
nameserver {{ DNS_SERVER }}

 3.执行结果
